2、做好外墙无机保温砂浆施工质量控制鉴于无机保温砂浆具备一些的节能环境保护特性,其物理性能较为稳定,且安全,如若在施工的过程中的操作技术处理完善,则可以在一些情况下保障建筑外墙的质量,进而延长建筑实体的使用寿命。在实际进行外墙施工过程中,主要的耗材为抹面砂浆、抗裂砂浆以及网格布等,而这些物料的选用标准以及技术操作标准需要严格把控,要根据进料台账与施工记录账目上所记载的物料生产厂家、进料数量等数据来执行,并做好每批施工物料的检验,只有在抽样检验合格以后,才能将物料投入到实际施工环节之中。除此以外,还要注意的施工环节便是无机膨胀玻化微珠保温砂浆物料的施工处理环节,需要将保温层与基层之间粘结牢靠稳固,以免脱层等不良现象发生,而且,在涂抹无机膨胀玻化微珠保温砂浆物料的过程中,尽可能涂抹两遍以上,每遍间隔24h 左右,并在涂抹以后做好养护处理,以免受到其它物质的撞、等。

保温砂浆单次抹灰过厚很容易产生空鼓开裂; 现场配置过程中如掺水量控制不好、搅拌方式、时间不科学,会使得保温砂浆和易性变差,出现干缩或滑坠。为此,在施工中采用下列措施减少保温层的开裂:

抗裂砂浆保护层由抗裂砂浆和增强网构成,抗裂砂浆由砂浆掺入聚合物抗裂纤维和外加剂、胶组成,增强网一般采用耐碱玻纤网格布,在二者共同作用下,可以加强抗裂效果,抵御干缩应力和温差应力,也能约束保温层的变形。贵州保温砂浆一分快三施工时应免雨天施工及5 级以上大风施工,增强网要平整、绷紧,紧靠饰面层一侧的砂浆中; 门窗洞口角部应力集中容易开裂,故周边应设置增强网,洞口阳角处增强网应外翻100mm,并在四角加设300mm × 300mm 的网格布。耐碱玻纤网格布搭接长度应保障不小于100mm,搭接处应充满砂浆。
